Q: How can I commit to secondary virginity?
A: I really admire those who make the choice to recommit to chastity after taking sex outside of marriage, because it's often just as hard to turn your life around as it is to stay chaste to begin with. Christ didn't condemn the woman who was accused of adultery; instead, he siad "Go and sin no more." Here are some practical tips for recommiting to chastity:
1. Make a list of a things that you've done that you regret doing (whether it was sex, the way that you've treated members of the opposite sex, clothing that you've worn, things that you've said etc). Go to confession!
2. Make a list of the reasons why you're waiting for your future spouse. Keep that list with you, and every time that you're tempted to go out and be in a situation where that temptation might arise, remind yourself of all the reasons why you're waiting.
3. Facing temptation: do something! Go for a run, play sports etc. Keep yourself busy.
4. Surround yourself with people who support your decision to commit to chastity. Good friends are invaluable in leading a clean life - true friends will challenge you to be the best person that you can possibly be.
